Hi Peter,
I just looked at the voltage settings for the APD Preamp
and have included them in this email. I do not have the
model #'s yet. Our group's post-doc is busy and hasn't
sent them to me yet. I will forward the information after
I get it.
To set up the voltages first cut one of the ends of the
molex cable. You will connect the power supplies to
the loose ends, and the preamp to the connector side.
The connector has two sides: a flat face, and one with
indentations. To understand the sequence of voltages
you should be holding the flat face pointing down.
>From left to right the voltages are:
- Negative 6 Volts
- Positive High Voltage
- Ground
- Positive 12 Volts
- This will be your output signal.
- The last wire is unused.
Let me know if you have any problems. The lab phone
number is 217 244 9663.
Thanks,
John
